I kinda felt the same way when I read that they were coming back after Season six's obvious logical wrap-up. It was such a perfect place to end. Everything wrapped up nicely over the course of an entire season.
I'll give it a chance (at this time I've yet to catch the new episodes), and I'll probably enjoy it since I've been a fan since the beginning.
The Ur example of this kind of post wrap-up continuation has to be Scrubs. Which ended so perfectly with JD leaving Sacred Heart to be nearer his son, Cox's emotional growth, Kelso leaving, Elliot and JD moving forward. Only to have too much reset to status quo when they decided to bring that abomination of a 9th season into the world. Parks & Rec 7 cannot possibly be as bad as that monstrosity.
